## What is ZenNotes?

Refining the QWERTY keyboard for one-handed use, ZenNotes is a text editor designed for writing that allows you to type in comfort for a long time while you relax or hold your iPad. You may find the ZenNotes keypad more compact than the QWERTY keyboard.

The ZenNotes keypad, also known as the TREWQ (pronounced "true-q") keypad, collapses the three rows of the QWERTY keyboard into six rows so that you can touch type using one hand. The key corresponding to the same finger on the other hand is located directly above, taking advantage of your existing touch typing muscle memory.

ZenNotes supports background music and allows you to manage, e-mail and print files from your iPad, as well as share and back up your documents using iTunes.

### 4/5 — Interesting

*2012-08-01, version 1.0*

I installed the free version of this app and then removed it. A day or so later I re-installed the free version and then bought the paid. I remain unsure if I can work the app into my routine, but honestly, I keep returning to it. 

The typing is accompanied by a satisfying little pop which is enjoyable once you get on a roll and learning the keyboard is coming pretty naturally. The method for choosing additional characters, not found on the keyboard, is fast and easy. 

I have been confounded by some of the things that one cannot do with this innovative little text editor but also feel the limitations to be somewhat freeing. The interface has a feeling that is unique on my iPad and for that alone, I would give the app high marks.  

All said, the program presents a challenge that I have had to make time for and the jury is still out on whether this will be time well spent, but it has been pretty interesting to see just how far I can run with it. Well done.
